T0 @ZZ whom z5 may concern:

Be it known that I, LYMAN B. GIBsoN, a citizen of the United States, anda resident of Addison, in the county of Steuben and State of New York,have invented certain new and useful Improvements in Scales; and I dohereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the saine, reference beinghad to the accompanying drawings, which form apart of thisspecification.

My invention relates to that class of counterscales known ascombination-scales57 audit has for its objects, iirst, to dispense withthe use of loose or separate weights; second, to construct acounter-scale provided with an improved index, by the use of which anyproportion of a commodity Iwith reference to its selling price may beaccurately and conveniently weighed, and, third, in the use of anadjustable reversibly auxiliary weight adapted to be used for thepurposes which will be hereinafter set forth.

To these ends my invention consists in the improved construction andcombination of parts, which will be hereinafter fully described, andparticularly pointed out in the claims. f

Referring to the annexed drawings, Figure 1 is a perspective view of myimproved combination counterscale. Fig. 2 is a vertical sectional viewtaken on line :v x, Fig. l. Fig. 3 is a vertical sectional. view takenon line y y, Fig. l; and Fig. 4 is a perspective detail view 0f thespring-weight EZ, which will be hereinafter described.

The same letters of reference indicate corresponding parts in all thegures.

Referring to the several parts by letter, A represents the frame whichsupports the hopper and weighing devices in operative position upon thesupport or platform A.

B represents a glass cylinder, which is lined with white pasteboard orother similar substance, which is marked in the manner which will behereinafter described, or the cylinder may be made of any suitableopaque material and the gradations marked upon the exterior thereof.rIhe glass cylinder is provided at each end with an end piece or cap, BB2, the said caps being provided with ilanges b, to adapt thorn to iitupon the ends of the glass cylinder B, a metal pipe or core, (l, passingthrough the glass cylinder and centrally through the end pieces thereof,being provided at its outer end with the bead or enlargement c, againstwhich the outer cap, B2, bears, while a pin, c', inserted into the saidcore against the outer face of the rea-r cap, B', serves to hold thecaps B and Bl firmly against the ends of the glass cylinder and causethem to revolve with the saine. The inner end of the metallic core@passes through a sleeve or bearing, A2, in the frame A, which ispivotally supported at c, a thumb-screw, a2, serving to secure the saidcore in its adjusted position. In the inner end of the core C slides arod, D, having on its inner end the weight D, the said rod being held inits adjusted position by the set-screw d. A tube, E, having on its enterend the weight F, slides in the outer portion oi' the core C, the saidtube E being marked to denote pounds and ounces, and having placedwithin it the curved spring-weight-FZ, which is held in position by itsspring or tendency to expand after it has been adjusted in the tube E,for the purpose hereinafter set forth. The tube E is provided with alongitudinal slot, e, through which the spring-weight E2 may be reachedto adj ust it back and forth in the tube as required.

An annular or ring shaped weight, F, which weighs one pound, slides uponthe glass cylinder B, having secured to it the annular flat ring G,(which I will for convenience term the price-list,,) the said price-listbeing marked with figures running from 10 to 100, and the metallicprice-listv being indented at a point between the ignres 10 and 10()(which are contiguous) at g to adapt the portion thus depressed to litand slide within a longitudinal groove, b2, on the outer face of theglass cylinder, thereby preventing the price-list and weight fromturning on the said cylinder as it is moved from one end of the cylinderto the other. The white pasteboard lining of the glass cylinder B isprovided with the longitudinal lines b3, the space between the saidlines corresponding to the spaces on the price-list Gin which the:figures are placed, these spaces IOO between the lines being dividedinto as many portions as the numeral which stands at the end of the saidspace. For instance, the longitudinal space on the lining opposite to orregistering with the numeral 10 is divided by transverse lines into l()spaces, while the space opposite the numeral S5 is divided into 85spaces, and so on.

An auxiliary weight H is secured on the outer end of the graduated tubeH', which slides in a sleeve or bearing, I, on the side of the pivctedsupporting-frame A, as shown in the drawings, the said tube beingprovided with a longitudinal slot, 7L', and having placed within it aSpringWeight, h, similar in construction to the weight E2 in the maintube E, the said auxiliary weight being used for the purposeshereinafter set forth.

To adjust the scale in its operative position, the glass cylinder B isfirst secured upon the core C, and the weight E pushed in close againstthe outer cap, B2, of the cylinder B, while the weight F is moved to theinner end, B, of the glass cylinder. By loosening the thumbscrews a2 andd the core carrying the cylinder may be moved in or out, and thus, inunison with the weight D', which is also moved in or out, caused tobalance the scale and hopper A, when the thumb-screws are tightened. Atest pound-weightis then placed in the hopper, and the weight F moved tothe outer endof the cylinder B, and if the weight F is found to be toolight in that position to balance the test pound-weight, which is causedby the glass cylinder B being too short-say onefourth of an inch-we'then loosen the thumb-screw a2 and draw the core C out from the sleeveA2 for one-fourth of an inch, thereby bringing the glass cylinder andweight F to a balance with the test-weight. The testweight is nowremoved, and the weight F moved back to the inner end of the glasscylinder, when the weight D is drawn out from the inner end of the coreC to balance the adj usted cylinder.

The weight E, (which is used in connection with or in combination withthe weight F when it is desired to weigh more than a pound of acommodity,) may be adj usted by first moving the annular weight F totheinner end of the glass cylinder B, placing atest poundweight in thescoop or hopper A3, and then drawing the graduated tube E out until itindicates one pound, when,if it is found that the weight E does notbalance the test-weight in the hopper through its being too light, thespring-weight E2 may be moved out toward the weight E', and by thusmoving the said springweight farther away from the pivotal point a ofthe balance the weight E will be caused to exactly balance thetest-weight in the hopper, while, if the weight Eis found to betooheavy, the spring-weight is moved in toward the inner end of the tubeE-that is, toward the pivotal point a of the balance-so as to cause thesaid weight to exactly balance the testweight in the hopper.

The manner in which the price-list operates in conjunction with thegraduated cylinder is as follows: If it is desired to sell seven 7ocents7 worth of a commodity which sells at ten cents per pound, theweight F is moved out from the inner end of the cylinder seven-tenths ofthe distance of the space which is divided into ten parts by itstransverse lines, which is seven-tenths of a pound or seven cents worthof that particular commodity. The same principle is followed in sellingcommodities at different prices; eighty cents worth of an articleselling at eighty-tive cents per pound being weighed by moving theannular pound` weight and price-list to the point where the space whichregisters with the numeral 85 on the price-list is marked 80, and so on.By the use of the sliding graduated rod E, having the weight E', the useof separate weights is entirely dispensed with.

rlhe auxiliary weight H, when its tube H is inserted through the sleeveor bearing I, in the position shown in the drawings-that is to say, withthe weight H on the same side of the pivotal point a as the main weightF--may be used to take out tare from the object being weighed. Forinstance, ifa certain proportion ofa commodity-say, for example, honeyisto be weighed, and it is necessary or desirable to place the same in avessel in the hopper, the said vessel may be first placed in the hopper,and balanced by the auxiliary weight H, and the commodity itself may bethcn placed in the said vessel and weighed by the main weight F, as willbe readilyunderstood.

The auxiliary weight H may be used to assist in weighing the article orcommodity in the hopper in combination with the weights F and E',thereby dispensing with loose weights, while, by reversing its tube H inthe sleeve or bearing l, it may be used in the following manner: lf acertain quantitysay two pounds-ofa commodity has been weighed in thescoop A3 by the weights F and E', and the purchaser desires that acertain quantitysay three quarters of a pound-should bc wrapped in aseparate bundle from the remainder of the same, the weight H, in itsreversed position, may be drawn out until its graduated tube I-Iindicates thrcequartcrs of a pound, thereby making the combined weightof the commodity in the scoop and the auxiliary weightH amount to twoand threesquarters pounds, while the weights F and E on the oppositeside of the pivotal point are adjusted to weigh two pounds,as beforestated. Threequarters of a pound of the commodity may be then removedfrom the scoop, this quantity being exactly determined by the reversedauxiliary weight H, it being only necessary to keep removing thecommodity from the scoop until the scale is balanced, the one andthrcequarters pound left in the scoop and the auxiliary weight adjustedat three-quarters of a pound exactly balancing the weights F and E onthe opposite side of the pivotal point; also, when it is desired toremove the scoop IOO IIO

A3 and place the article to be weighed or the vessel in which it is tobe placed directly upon the flat portion of the frame A, the auxiliaryweight H may be used in its re versed position to balance the cylinder Bin place of the scoop which has been removed.

Vhen the slotted tube H is inserted through the collar I in the positionshown in Fig. l, and the said tube has been drawn out to indicate, say,one-half pound, and a test onehalf -pound weight has been placed in thescoop A3, if the Weight H is then found to be too light or too heavy toexactly balance thetest-weight in the hopper the springweight h isadjusted until the weight H eX- actly balances the test-weight, beingadjusted in the same manner and for the same purpose as thespring-weight E2 in the tube E.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of my improvedcombination counter scale will be readily understood without requiringfurther explanation.

It will be seen that my invention dispenses with the use of separateweights, and may also be used to take out tare and subtract from ordivide the commodity being weighed, while any proportion of a commoditywith reference to its selling price may be accurately and convenientlyweighed. It will be seen that my improved scale is also exceedinglysimple in construction, and is therefore cheap to manufacture, and notliable to ,get out of order.

Having thus described my invention, what I claim and desire to secure byLetters Patent of the United States, isv l. The combination, with thepivoted supporting frame, of the graduated cylinder having the coreadapted to be secured adjustably in the said supporting-frame, as andfor the purpose shown andset forth.

2. The combination, with the pivoted supporting frame, of the graduatedcylinder having the core adapted to be adjusted longitudinally in asuitable bearing in the said supporting-frame, as shown, for the purposeset forth.

3. The combination, with the pivoted support-ing frame, of the coresupporting the graduated cylinder carrying the main weight and adjustably secured in the forward portion of the said supporting frame, andthe rod having the end weight and adapted to be secured adj ustably inthe inner end of the said core, as shown, for the purpose set forth.

et. The combination, with the pivoted supporting-frame and the centralcore, of the graduated metallic tube having the Weight on its outer end,and adapted to slide in the outer end of the said core, substantially asset forth.

5. The combination, with the pivoted supporting-frame and central core,of the graduated metallic tube having the weight on its outer end andprovided with the adjustable interior spring-weight, for the purpose setforth.

6. The combination, with the pivoted supporting-frame and weighingapparatus, of the adjustable and reversible auxiliary graduated tubehaving the end weight, and adapted to operate in the manner and for thepurpose set forth.

7. The combination, with the pivoted supporting-frame and weighingapparatus, of the adjustable and reversible auxiliary graduated tubearranged to operate in the manner and for the purpose set forth andhaving the adjustable interior spring-weight, as set forth.

8. The combination, with the pivoted supporting-frame and the adjustablecore carrying the graduated cylinder having the adjustable weight andprice-list, of the graduated adj ust-able tube having the weight on itsouter end and provided with the adjustable springweight, for the purposeset forth.

In testimony that I claim 'the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.

LYMAN B. GIBSON.
